That seems quite self explanatory. Your grafana is trying to connect
as "grafana" role, on "grafana" database from 10.240.1.45, and your
pg_hba.conf file doesn't allow it. I'm not sure how to configure that
on AKS but you need to either authorize it or configure grafana to use
some other credentials that are already allowed, like this one:

(assuming that this psql connection is allowing other IP). See
https://www.postgresql.org/docs/current/auth-pg-hba-conf.html for more
details about the pg_hba.conf file.
